Science and the Infinite; Or, Through a Window in the Blank Wall

What if everything you see is only a wall, and the real world lies behind it? Klein's 1918 meditation begins with this arresting premise: our senses build a "blank wall" between us and truth, and most of us never find the window. Drawing on his intimate encounters with the dying, Klein writes not as a distant philosopher but as someone who has watched the veil lift at life's edge. He argues that our everyday worries and the material world cloud perception of deeper truths that await anyone willing to look. The book offers a series of "views" through that imagined window, each one inviting readers to question whether the physical universe is really the final answer. Klein's tone carries quiet urgency, shaped by witnessing what death reveals. This is philosophy as spiritual autobiography, an early twentieth-century search for meaning that resonates with anyone who has ever wondered what lies beyond the obvious.
